/**
 *
 *  自定义属性工具类
 *
 *  注意： 宽高都为 match_content 且无实际内容时构造方法不会调用
 *  使用方法：
 *  xxx extends Component
 *  获取自定义属性：
 *  String count = AttrUtils.getStringFromAttr(attrSet,"cus_count","0");
 *
 *  属性定义：
 *  布局头中加入  xmlns:hap="http://schemas.huawei.com/apk/res/ohos" 使用hap区分自定义属性与系统属性
 *  即可使用 hap:cus_count="2"  不加直接使用ohos:cus_count="2"
 *
 *  与xxx区别：xxx在xml预先定义好属性，可通过app: 点选，ohos暂未发现对应方法
